Pulmonary function was evaluated in 138 patients with pectus excavatum, paying particular attention to the degree of severity of chest deformity. We defined the severity of deformity quantitatively based upon a computed tomographic index obtained from a computed tomogram. We recognized a positive relationship between computed tomographic index (x) and percent vital capacity (y), as follows: y = 137x + 58 (n = 138, r = 0.61, p < 0.05). Pulmonary function tests were performed from 2 to 42 months postoperatively. Vital capacity decreased about 10% from the baseline value during the initial 2 months after surgical treatment and recovered to the preoperative level by 1 year after surgery. At 42 months after surgical correction, the pulmonary function was maintained at the baseline level and the severity of deformity was significantly improved. Surgical procedures for the treatment of pectus excavatum--sternocostal elevation and sternal turnover--resulted in an excellent cosmetic result but did not importantly affect respiratory function.
对138例漏斗胸患者的肺功能进行了评估，特别关注胸部畸形的严重程度。我们根据从计算机断层扫描获得的计算机断层扫描指数对畸形的严重程度进行了定量定义。我们认识到计算机断层扫描指数（x）与肺活量百分比（y）之间存在正相关关系，如下所示：y = 137x + 58（n = 138，r = 0.61，p < 0.05）。术后2至42个月进行肺功能测试。手术后最初2个月内，肺活量较基线值下降约10%，术后1年恢复到术前水平。手术矫正42个月后，肺功能维持在基线水平，畸形严重程度显著改善。漏斗胸的手术治疗方法——胸骨肋骨抬高术和胸骨翻转术——取得了极佳的美容效果，但对呼吸功能没有重要影响。
